Introducing myself

I am learning English because it is necessary in for my work (or "for my job"). I watch movies in English and read a lot of books too, but what I really need to improve are my conversation skills.
My native language is French. I am really good in it, in speaking and in writing (or "both in speaking and writing" / "in both speaking and writing").
I enjoy outdoor sports like hiking. I am also doing jogging regularly and some yoga. I am have been learning piano for four years. I like to have fun with my friends and do some sports.

Great!! You can say "I am doing jogging," but it is not necessary.

Recommended study topics: Dependent prepositions, present perfect tense, comma use.
